* implement write-only colletions, typing for dynamicMike Bayer2022-10-061-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For 2.0, we provide a truly "larger than memory collection" implementation, a write-only collection that will never under any circumstances implicitly load the entire collection, even during flush. This is essentially a much more "strict" version of the "dynamic" loader, which in fact has a lot of scenarios that it loads the full backing collection into memory, mostly defeating its purpose. Typing constructs are added that support both the new feature WriteOnlyMapping as well as the legacy feature DynamicMapping. These have been integrated with "annotion based mapping" so that relationship() uses these annotations to configure the loader strategy as well. additional changes: * the docs triggered a conflict in hybrid's "transformers" section, this section is hard-coded to Query using a pattern that doesnt seem to have any use and isn't part of the current select() interface, so just removed this section * As the docs for WriteOnlyMapping are very long, collections.rst is broken up into two pages now.

* inline mypy config; files ignoring type errors for the momentMike Bayer2022-04-281-0/+2
| | | | | | | | | | | | | | | | | | | to simplify pyproject.toml change the remaining files that aren't going to be typed on this first pass (unless of course someone wants to type some of these) to include # mypy: ignore-errors. for the moment, only a handful of ORM modules are to have more type checking implemented. It's important that ignore-errors is used and not "# type: ignore", as in the latter case, mypy doesn't even read the existing types in the file, which makes it impossible to type any files that refer to those modules at all. to simplify ongoing typing work use inline mypy config for remaining files that are "done" for now, indicating the level of type checking they currently have.

* pep-484 for sqlalchemy.event; use future annotationsMike Bayer2022-02-151-0/+2
| | | | | | | | | | __future__.annotations mode allows us to use non-string annotations for argument and return types in most cases, but more importantly it removes a large amount of runtime overhead that would be spent in evaluating the annotations.

* Build out new declarative systems; deprecate mapper()Mike Bayer2020-09-101-4/+6
| | | | | | | | | | | | | The ORM Declarative system is now unified into the ORM itself, with new import spaces under ``sqlalchemy.orm`` and new kinds of mappings. Support for decorator-based mappings without using a base class, support for classical style-mapper() calls that have access to the declarative class registry for relationships, and full integration of Declarative with 3rd party class attribute systems like ``dataclasses`` and ``attrs`` is now supported.

* Fixes for uselist=True with m2o relationshipsMike Bayer2019-07-181-2/+4
| | | | | | | | | | | | | | | Fixed bug where a many-to-one relationship that specified ``uselist=True`` would fail to update correctly during a primary key change where a related column needs to change. Fixed bug where the detection for many-to-one or one-to-one use with a "dynamic" relationship, which is an invalid configuration, would fail to raise if the relationship were configured with ``uselist=True``. The current fix is that it warns, instead of raises, as this would otherwise be backwards incompatible, however in a future release it will be a raise.

* Post black reformattingMike Bayer2019-01-061-1/+2
| | | | | | | | | | | | | Applied on top of a pure run of black -l 79 in I7eda77fed3d8e73df84b3651fd6cfcfe858d4dc9, this set of changes resolves all remaining flake8 conditions for those codes we have enabled in setup.cfg. Included are resolutions for all remaining flake8 issues including shadowed builtins, long lines, import order, unused imports, duplicate imports, and docstring issues.

* Run black -l 79 against all source filesMike Bayer2019-01-061-9/+14
| | | | | | | | | | | | | | This is a straight reformat run using black as is, with no edits applied at all. The black run will format code consistently, however in some cases that are prevalent in SQLAlchemy code it produces too-long lines. The too-long lines will be resolved in the following commit that will resolve all remaining flake8 issues including shadowed builtins, long lines, import order, unused imports, duplicate imports, and docstring issues.

| | | | | | | | | | | | | | | | | | | | | fully usable within declarative relationship configuration, as its string classname would not be available in the registry of classnames at mapper configuration time. The class now explicitly adds itself to the class regsitry, and additionally both :class:`.AbstractConcreteBase` as well as :class:`.ConcreteBase` set themselves up *before* mappers are configured within the :func:`.configure_mappers` setup, using the new :meth:`.MapperEvents.before_configured` event. [ticket:2950] - Added new :meth:`.MapperEvents.before_configured` event which allows an event at the start of :func:`.configure_mappers`, as well as ``__declare_first__()`` hook within declarative to complement ``__declare_last__()``. - modified how after_configured is invoked; we just make a dispatch() not actually connected to any mapper. this makes it easier to also invoke before_configured correctly. - improved the ComparableEntity fixture to handle collections that are sets.

become an externally usable package but still remains within the main sqlalchemy parent package. in this system, we use kind of an ugly hack to get the noseplugin imported outside of the "sqlalchemy" package, while still making it available within sqlalchemy for usage by third party libraries.
